MECHANISM OF THE INHIBITING ACTION OF ELECTROLYTES ON THE MICELLAR EFFECT IN ALKALINE-HYDROLYSIS OF P-NITROPHENYL ETHYL CHLOROMETHYLPHOSPHONATE

The influence of KCl, KBr and sodium salicylate (NaSal) on the micella r effect of cetylpyridinium bromide in the alkaline hydrolysis of p-ni trophenyl ethyl chloromethylphosphonate has been studied and the effec ts of electrolytes on the rate constant and surface potential compared ; based on the data obtained, it can be concluded that the reaction in hibition is determined both by a change in the structure and propertie s of the micellar aggregates and by a decrease in the concentration of the nucleophile in the micelles due to a decrease in the surface pote ntial.
